Dayton Audio LW14-40 | 0.40 mH | 0.15 Ω | 3% | 14 AWG

The Dayton Audio LW14-40 is a precision-engineered air core inductor designed to elevate the performance of high-fidelity loudspeaker crossover networks. As a perfect layer coil, it delivers consistent and reliable inductance, making it an essential component for audiophiles and DIY speaker builders who demand accurate frequency division and minimal signal degradation.

This inductor is ideally suited for use in passive crossover designs within home audio speakers, studio monitors, and custom sound systems. Its low DC resistance of just 0.15 Ω ensures minimal power loss and heat generation, preserving the integrity of the audio signal even under demanding conditions. Whether you are constructing a new set of speakers or upgrading an existing design, the LW14-40 provides the precision needed for clear, detailed sound reproduction.

Technically, the LW14-40 offers an inductance of 0.40 mH with a tight tolerance of ±3%, ensuring consistent performance across units. It is wound with 14 AWG wire, which contributes to its low resistance and excellent current handling. The air core construction eliminates core saturation and distortion, while the compact dimensions of 51 x 28.5 mm allow for easy integration into most crossover boards. With an RMS power tolerance of 8 watts, this coil is built to handle moderate power levels with reliability.

In summary, the Dayton Audio LW14-40 air core inductor combines precise specifications with robust build quality, making it a trustworthy choice for achieving accurate crossover performance in your speaker projects.
